civilizations. in colorado and new mexico, native americans built thriving towns. in the rain forests of mesoamerica, the ancient maya created magnificent city-states. here three million people once lived. in the earliest cradle of civilization, ancient mesopotamian farmers once made these deserts bloom. halfway around the world, in california, are clues to understanding the fall of mesopotamia, as farmers here struggle to overcome a threat to this fertile garden land. the ruins of ancient societies may hold keys to our own survival as, out of the past, archaeologists explore one of the greatest of mysteries -- the decline and fall of grand civilizations. mission control: ignition... and liftoff. liftoff... keach: for more than five millennia, humankind has seemed to dominate earth, both creating and destroying grand civilizations. each of these human experiments has changed our planet. this high vantage point brings us a new and sobering view. for the first time, we behold our world as finite, limited. on the darkened face of earth, the lights of cities record the expansion of our ki

of the primordial forest and sunk its roots into the soil. today, we know the region by its countries-- mexico, honduras, el salvador, belize, and guatemala. but long ago, it was the world of the maya. not an empire, nor a country, the classic maya culture flourished from the third to the ninth century in a far flung collection of city-states. at palenque, tonina, bonampak and other cities, dynastic kings ruled absolutely, controlling trade and tribute. they presided over intricate hierarchies of nobles and officials at courts resplendent with works of art. maya culture, shrouded in a mystery as dense as the forests in which it took root, revealed itself fitfully over three centuries. when the ruins in the jungle were first discovered, there was no way of understanding how the civilization was organized. so it's really through the inscriptions that we've been able to identify kings, to find out their capitals, their seats of power. and through this, we recognize now that there were many kingdoms. there was no unified maya state. there wasn't even just a few states. there were many, many states

funding for this program was provided by... at vacation retreats in ancient mexico, aztec kings bathe while their armies sack and burn a remote town. thousands of captives are marched to the capital where their hearts are offered to gods who sanctioned conquest. every city and town in the empire pays tribute in exact amount and kind as specified by the aztecs, or risks horrible consequences. in the forests and jungles of other realms, maya kings rule great cities with the force of their own personalities. they build temples and huge stone billboards to prop up royal dynasties that have little actual power. they perform gruesome rituals that require the skins of other people. they go to war and capture players for their ball games -- games where the losers never play again. today, inside ancient pyramids, archaeologists face real danger to bring the story of these kings and their politics out of the past. before the arrival of europeans, two extraordinary civilizations flourished in mesoamerica. both the aztecs and the maya had cultures of startling sophistication, and political

, teotihuacan, dominated the basin of mexico. atop a hill in the valley of oaxaca, sits monte alban, the royal center of a mighty kingdom. and in the forests and jungles of guatemala, maya city states once reigned over thousands of square miles. this is mesoamerica. at about a.d. 700, three great civilizations had emerged here. the realms of the maya. the power of the great city of teotihuacan. the zapotec kingdom of monte alban. for many scholars the differences between new and old-world civilizations suggested an independent course of history -- that each evolved on its own. this led to another and deeper insight -- beneath these differences may lie a grand and universal similarity, a parallel course of human evolution throughout the world. we now know that all humans once lived nomadic lives. we gathered wild plants and followed the migrations of animals. our lives were lived in small bands. everything was shared. no one had more power or wealth then anyone else. 10,000 years ago, people began to farm and live in permanent settlements. soon, villages, towns and cities evolved and life chang

pose a danger to swimmers and surfers. two miles to the south is the city of tijuana, mexico. almost half of the homes and businesses in this rapidly growing urban area are not connected to a sewer system. ababout half a mile short of that two miles is the mouth of the tijuana river, where a million acre watershed pours water and unconnected sewage from homes that are unsewered in mexico down into the watershed, and that's out the mouth of the river where the sewage flows north or south, depending on ocean currents. the rapid growth of industry along the border has also created severe pollution problems. most mexican factories do not treat their wastes before dumping them in the ocean. carolyn powers: you don't see toxics in the waters so the beauty that you see behind me is very deceptive in that you don't see the chloroforms, you don't see the lead, you don't see the arsenic, you don't see the toxins discharged from the maquiladoras in mexico that come down the tijuana river untreated and actually pollute the marine mammal fisheries, and as well as the recreational users here in im

sensibility, that we are border people, that we live in the space between both the united states and mexico, that we are of neither and of both, and that we are, particularly, a people who...have a political point of view. and this is essentially the bones of the work. this will be like the bones -- what will hold the whole piece together so that not any part of the image will fly to a place. not an arm, not a leg, not a form, not a mountain, not a rock, will be placed haphazardly. it will be placed with intention. it will be placed in a musical rhythm, one form to the other. increasingly, more people are understanding that the creative act is one that begins at the very point of research or thinking -- that that is the beginning of the art. and as you look at our site over here, you can see that there's a couple of major ways that people will see the piece. people coming right in this door will walk through this part of the room, and come into the center of the room, and they'll have a direct view of the overall wall. the difference between the way i work and the way artists have worked hi

516 million tons per year from its headwaters in minnesota all the way to the gulf of mexico. along the great length of this river, the process of deposition sometimes causes serious problems. if bars build up in important areas of navigation, they can disrupt shipping and regional commerce. in the industrial corridor between new orleans and baton rouge, lies one of north america's most important navigational routes. in order to keep the river open to the many ocean-going vessels which use it year-round, the united states army corp of engineers must continually grapple with the forces of nature. one frequent trouble spot lies just south of baton rouge in a stretch of the river called red eye crossing. here the river tends to deposit sediment, threatening to close the channel to deep-water ships. a detailed study of red eye crossing is currently underway at the army corps' waterways experiment station, or wes, in vicksburg, mississippi. tom pokrefke is chief of the river engineering branch and heads the red eye investigation. the problem that we're studying on the red eye crossing is

( music ) narrator: the thousand yearsgo in souern mexico, an unprecedent culture flourished in the jungle nearhe gulf coast. rivers meandering through the hot, tropical lowlands were the region's lifeblood. theswaterwayfor transportion and trade encouraged agriculture. annual floods left deposits of fertile soil, ideal for growing maize, squash and beans. more than two thousand years later, the aztecs called this region "olman," or "rubber country," the name of the peoples. who dwelled there in antiquity is lost, but they have become known as olmec. to express their political and religious beliefs, the ancient olmec invented imagery of spellbinding power. they carved monumental sculptures fm volcanic rock without mel tools, ing hammers and chisels made ostone. they transported massive blocks of basalt, weighing up to 20 ns, across miles of teory thout benefit of the wel. they built the first pyramid in the americas, rising 100 feet anma of ren the anhalf millionubic ft ofd-pa eth. they fasoned delicate, and often deeply expressive, works of art in ceramic, serpentine and jad

functioned as a gateway city through which goods from across central mexico, and perhaps even western mexico, funneled into chalcatzingo and then moved eastward toward the gulf coast. obre in the valley of mexico,n the tskirts ofexico city, archaeologts have excavated graves from about 900 b.c. containing clay figures and pottery of the olmec style. other olmec objects have been found in the surrounding highlands and as far south as honduras and costa rica. the wide distribution of olmec works of art suggests that many centers participated in the development of the style. distt vies were evidentlyy linked through trade in cacao, white clay for pottery, obsidian, animal skins, and the most precious commodity of all, jade. its nearest known source is in guatemala. this vast tradg network paved the way for the exchange of ideas aselas goo, and led to the ergence of a pan-mesoameran olmec style. miguel covarrubias defined this new aesthetic: "olmec artists were mainly concerned with simplicity and sensual realism of form, with the human being made up of solid, ample masses. they delighted in the
